Science theories are different than regular theories.
Yes, in that science theories can (in the vast majority of cases) be proven or disproven.
The stuff we can't prove - well, we might be able to prove or disprove in the future, once our science has advanced some more.
But they never are proven. If they were, they would no longer be theories of any kind. They would be laws or facts.
Yeah, they are proven, of course they are. You can't say no science is ever proven! I don't know whether you are typing that on a phone or a laptop or whatever, but there is a hell of a lot of proven science that built that device. You really think it's all guesswork?
Here's a cell phone. It wasn't created just by someone saying I'll get some green stuff and put some silver stuff on it.
